Comment (by nacin):

 Some thoughts:
  * The is_null() checks can also go. See #21321.
  * Not sure if there is a need to cast `$next['value']` to an array. If we
 found an element in `$wp_filter[ $tag ]` (as in, `!== false`), it's going
 to be an array of functions tied to a priority, and not anything else.

 Both changes should shave a bit of time off of this.
